You could telnet to the SMTP port and type the commands to
deliver one message to one good and one bad recipient.

You will discover that Postfix rejects the bad user and
accepts the good user, and that it will accept the message.

You are mistaken. You have no evidence whatsoever that Postfix
rejects the entire message.

It is known that SOME SMTP CLIENT programs will give up delivering
a message when one recipient is not accepted, even when the other
recipients are good.
